本发明涉及一种照明装置，其包括框体、光学底板、光源以及光学膜片。光学底板设置于框体内，并在中央处具有第一隆起部，第一隆起部具有至少一个反射面。光源设置于框体内，并邻设于光学底板的周缘，光源与反射面对应设置，并具有多个发光元件，发光元件分别具有一光轴方向，光轴方向朝向第一隆起部。光学膜片设置于框体，且光学底板的第一隆起部是朝向光学膜片隆起。
An illumination apparatus includes a frame, an optical base plate, a light source and an optical film. The optical base plate is disposed in the frame and has a first protrusion portion at the center of the optical base plate. The first protrusion portion has at least a reflective surface and a top surface, which are connected with each other. The light source is disposed in the frame and located adjacent to the periphery of the optical base plate. The light source is disposed corresponding to the reflective surface and has a plurality of light-emitting elements. Each light-emitting element has an optical axis direction, and the optical axis directions extend toward the first protrusion portion. The optical film is disposed at the frame, and the first protrusion portion of the optical base plate protrudes toward the optical film.
